Medication details


Azithromycin is an antibiotic medication that is used to treat a wide range of bacterial infections. It belongs to a class of antibiotics known as macrolides, which work by preventing bacteria from producing the proteins they need to survive. Azithromycin is commonly used to treat respiratory tract infections, such as bronchitis and pneumonia, as well as skin and soft tissue infections, such as impetigo and cellulitis. It can also be used to treat sexually transmitted infections, such as chlamydia and gonorrhea. Azithromycin is available in its' oral form and can be taken once or twice a day, depending on the type of infection being treated. This medication is generally well tolerated and can be an effective treatment option for those suffering from bacterial infections.


Read this leaflet carefully before starting your treatment with Azithromycin. Keep it for future reference. If you have any questions, consult your doctor or pharmacist. This medication is prescribed for your use only. Do not share it with others, as it may harm them even if their symptoms are similar to yours.

Always follow your doctor's or pharmacist's instructions when taking Azithromycin. The recommended doses are as follows:
For adults and children weighing 45 kg or more: A 3-day course of 500 mg once daily, or a 5-day course with varying doses.
For infections caused by Chlamydia trachomatis: A single 1000 mg dose.
Special Considerations
Children under 45 kg should use other forms of the medicine.
Patients with kidney or liver problems may require dose adjustments.
Elderly individuals can use the same dosage as adults.
Take the tablets with water, with or without food.


The active ingredient in Azithromycin 250mg Tablets is azithromycin dihydrate, which plays a pivotal role in inhibiting bacterial protein synthesis. This ensures the disruption of bacterial growth and curbs the progression of infections. Inactive ingredients, such as cellulose compounds and other pharmaceutical excipients, contribute to the tablet's stability and facilitate its administration.
